    Exclamation Should i shoot .223 or 5.56?

    I just got my AR yesterday.
    And someone told me it was bad to shoot 5.56 from this, or it could of been the other day around and been .223.

    I've always thought they were the same bullet.

    But should i be shooting .223 like the remington ones at walmart that say .223 on the box?

    Or look for ones that say 5.56 NATO?

    Here is my gun




    Its a Double Star 15 CAR / 16" / HBAR

    The barrel will be stamped for caliber. If it's stamped for 5.56 NATO shoot whichever you like.
    If it's stamped for .223. Shoot .223 only.

    You'll also need some kind of riser to get your red dot sight higher so you can actually see over the front post.

    Im on a budget so im going to get some iron sights to do me for now.
    I have to buy the .22 conversion kit first, then im going to get a scope when my birthday comes around.

    This is correct. Just to further educate the OP. The barrel marking refers to what the barrel's chamber is set up for. While .223 and 5.56 are the same size round, 5.56 fires at a higher pressure and therefore requires a slightly larger chamber.

    Where can i get 5.56 bullets?
    When i go to walmart all i see is the Remington .223's
    At the pawnshop they have some wolf .223's but they are steel casing. but there only like 5 dollars for 20.

    i shot about 200 yesterday with no jams, so i guess there fine.

    As far as bullets go, they're both the same and are actually .224.

    You can safely shoot .223 or 5.56 loaded cartridges out of your rifle.

    Wolf is well suited for that firearm and your application.

    I'd say practice with what's cheap and reliable.

    The thought process being to shoot as frequently as possible.

    That being said, mixing wolf and brass, without cleaning the chamber I've heard you can run into issues.

    The Lacquer on the steel ammo will accumulate on the chamber, steel doesn't expand or change as much in shape when the casing is shot as brass.

    The problem is, the expansion of the brass into the residual lacquer will end up in the casing getting stuck.

    I'll be shooting .223 Rem Wolf once I complete my BCM AR.

    ETA: That being said, I'd get 5.56mm for Self Defense, and zero your optic and BUIS to that ammo, depending on the twist, would depend on the grain bullet you get.

    But then again, some people shoot 75 gr 5.56mm out of 1/9 twist barrels with no issue.

    So YMMV.
